A spokeswoman for the Larimer County, Colo., district attorney tells E! News exclusively that the sheriff's department has not yet submitted enough evidence to formally press criminal charges against Balloon Boy parents Richard and Mayumi Heene for tricking the world into believing their 6-year-old son had been whisked away on a homemade flying saucer.

"They did bring [the report] over a week ago, and we asked for additional reports and information," says D.A. spokeswoman Linda Jensen. "We're waiting for that from the sheriff's office before we make a final charging decision."

Jensen says she expects the new information "by the end of the week."

Apparently the D.A. needs more than Mayumi's apparent confession to bring down the hammer.

Previously, Sheriff Jim Alderden said he expects Richard and Mayumi to face counts of contributing to the delinquency of a minor, attempting to influence a public servant and conspiracy.

While they're at it, how about adding a count or two for trying to foist Boxter on us?
